APPLICATION HLED IULYII'I. 191l- I Patented Apr. 30,1918.

. chamber 8 is also in treatment into said space.

6 is a pipe in connection, at one end, with a reservoir A. either directly or, as shown, through a heater 3, and at the other end through one ormore branches, two'are shown, with the interior of the vessel 1. The heater B is provided for heating up the extracting agent as it passes therethrou'gh' on its Way to the vessel and so that the vessel 1 is filled. with extract ing agent at the proper temperature. By means of the pipe 6 the extracting agent can be introduced Within the vessel 1 at one or more places in its length and among the material with which the vessel is charged.

are coils connected with a steam gener-- ator; the steam coils '2 are contained within the vessel 1 and serve to heat up the contained charge of material and to maintain the heat of, or heat up, the extracting agent introduced through pipe 6. The chamber I 8 contains steam heating coils 9 and is also provided WithIa manhole 14 through which access can be obtained to its interior. The connection with a still C (or stills) and, through the still (or stills) with a condenser D (or condensers). The oils, fats or greases or gelatin under the combined actions of heat and the extracting agent are extracted from. the charge of material contained in the vessel 1 and pass therefrom through the grating or grid 5 into the chamber 8, wherein to further heating action of the steam coils 9. Extracting agent also passes from the vessel 1 into the chamber 8, and this extracting agent, together with the extracted oils, fats or. greases o: gelatin, are passed by gravity into the still C in which the extracting agent is separated from the oils, fats or greases or gelatin and is led through'a pipe 10 to the condenser D in which it is condensed and then delivered to the reservoir A.

.The still C can be placed otherwise and the oils, fats or greases or gelatin delivered thereto by a pump. The distillation of the they are subjected.

nee-sass oils, fats or greases or gelatin may take place under vacuum, if desired. The vessel may be fitted, if necesssny, and as shown, with mechanically driven stirrers 21. The vessel 1 is also connected by a pipe 11, to which the pipe 10 is shown connected with the condenser D so that extracting agent in vaporous form may pass to the condenser D. The pipe 10 may, instead of being connected indirectly with the condenser, be connected directly thereto. The pipes 6, 11 are provided with suitable regulating valves.

I claim 1. Apparatus for the extraction of oils, fats, greases or gelatin from materials containing or yielding the same, comprising a vessel inclined in the direction of its length, means for heating said vessel, a chamber communicating directly with said vessel at its lower end and underside, heating means provided in said chamber, a still communicating with said chamber, and a condenser in communication with said still.

2. Apparatus for the GXL1.iClLlOl] of oils, fats, greases or gelatin from materials containing or yielding the same, comprising a vessel inclined in the direction of its length, which dimension is greater than its transverse or other dimensions, a chmnber communicating with said vessel. at its lower end and underside, a grid disposed between said vessel and chamber, means for heating said vessel and chamber, further means connecting said chamber to a still, condenser and reservoir for the extracting agent, and means for heating the extracting agent passing from said reservoir to the vessel.

In testimonywhereof I have signed this specification in the presence of two subscribing Witnesses.
